OS for EX Series Ethernet Switches, Release 10.4
Forwarding classes allow you to group packets for transmission. Based on forwarding
classes, you assign packets to output queues.
By default, four categories of forwarding classes are defined: best effort, assured
forwarding, expedited forwarding, and network control. EX Series switches support up
to 16 forwarding classes.
You can configure forwarding classes in one of the following ways:
Using statement—You can configure up to 16 forwarding classes and you can
class
map multiple forwarding classes to single queue.
Using queue statement—You can configure up to 8 forwarding classes and you can
map one forwarding class to one queue.
This example uses the
class
To configure CoS forwarding classes, map the forwarding classes to queues:
[edit class-of-service forwarding-classes]
user@switch# set class be queue—num 0
user@switch# set class ef queue—num 1
user@switch# set class af queue—num 2
user@switch# set class nc queue—num 3
user@switch# set class ef1 queue—num 4
user@switch# set class ef2 queue—num 5
user@switch# set class af1 queue—num 6
user@switch# set class nc1 queue—num 7

You can define CoS forwarding classes on an EX Series switch using the J-Web interface.
Assigning a forwarding class to a queue number affects the scheduling and marking of
a packet as it transits a switch.
